DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] like Figures 1 to 9 As shown, an anti-segregation device for pouring concrete for super-high-rise steel pipe columns includes a hopper-type pouring hopper 1 and a pouring straight pipe 2. A circular reinforcement ring 7 is welded to the outer wall of the upper part of the pouring hopper 1, and four lifting ears 8 arranged in a circular array are welded to the top of the reinforcement ring 7, and the lifting ears 8 are welded to the pouring hopper 1.

[0028] A discharge pipe 3 is fixedly connected to the bottom end of the casting hopper 1, and a gate 4 for controlling the opening and closing of the discharge pipe 3 is installed in the middle of the discharge pipe 3. A first gate inlet and outlet 9 perpendicular to the central axis of the discharge pipe 3 is provided in the middle of the discharge pipe 3, and a circular reinforcement pipe 10 is welded to the outer side of the middle part of the discharge pipe 3. A second gate inlet and outlet 11 connected to the first gate inlet and outlet 9 is provided on one side of the reinforcement pipe 10. One side of the gate 4 is hinged to the reinforcement pipe 10 through a first hinge shaft 12, and a round rod-shaped handle 13 is fixed to the other side of the gate 4.

[0029] A vertical first pin hole 14 is provided on the gate plate 4 on one side close to the round rod-shaped handle 13, and a vertical second pin hole 15 is provided on the reinforcing tube 10 on one side away from the first hinge shaft 12. When the second pin hole 15 is aligned with the first pin hole 14, a plug 16 is inserted into the second pin hole 15 and the first pin hole 14, and the plug 16 is tied to the discharge pipe 3 with a rope, and the plug 16 is inserted into the aligned second pin hole 15 and the first pin hole 14 to prevent the gate plate of the anti-segregation device from loosening during the lifting process, and to prevent the concrete from being discharged from the discharge pipe to the outside of the steel column during the lifting process of the anti-segregation device, causing concrete waste.

[0030] N wave-shaped buffer elbows 5 are installed between the discharge pipe 3 and the casting straight pipe 2, where N is a positive integer.

[0031] When N is a positive integer greater than 1, the planes of the two upper and lower adjacent buffer bends 5 are perpendicular to each other, which promotes the concrete to change its flow direction in the two upper and lower adjacent buffer bends 5 in four directions, namely, front, back, left, and right, and further promotes the concrete to turn over and stir in the buffer bends 5. The angle between the connecting line between the two adjacent curved sections of the buffer bend 5 and the horizontal plane is 45° to 60°, that is, in order to play a role in decelerating and buffering the concrete, it is also necessary to ensure that the concrete can flow freely in the buffer bend to prevent the concrete from being blocked in the buffer bend.

[0032] The height of the casting straight pipe is 50 cm, the inner diameter of the discharge pipe 3 is equal to the inner diameter of the buffer elbow 5, and the inner diameter of the casting straight pipe 2 is equal to the inner diameter of the buffer elbow 5.

[0033] The buffer elbow 5 is connected and fixed with the adjacent discharge pipe 3, cast straight pipe 2 or buffer elbow 5 by a quick-connect clamp 6. Specifically, a first connecting ring 17 is welded to the bottom end of the discharge pipe 3 and the bottom end of the buffer elbow 5, and a second connecting ring 18 is welded to the top end of the buffer elbow 5 and the top end of the cast straight pipe 2; the quick-connect clamp 6 includes a fan-shaped first clamping strip 19, a fan-shaped second clamping strip 20, and an internal threaded tube 21. The inner middle part of the first clamping strip 19 and the inner middle part of the second clamping strip 20 are both provided with a fan-shaped clamping groove 22, and the first connecting ring 17 and the adjacent second connecting ring 18 are clamped in the clamping groove 22; the first end of the first clamping strip 19 is fixedly connected to two first hinge blocks 23 symmetrically arranged in the upper and lower parts, and the middle part of the first end of the second clamping strip 20 is fixedly connected to the inner middle part of the second clamping strip 20. A second hinge block 24, the first hinge block 23 and the second hinge block 24 are hinged through a second hinge shaft 25; the second end of the second clamping strip 20 is fixedly connected with two third hinge blocks 26 which are symmetrical up and down, and a movable bolt 28 is hinged between the two third hinge blocks 26 through a third hinge shaft 27, and the second end of the second clamping strip 20 is fixedly connected with a U-shaped plate 29. After the movable bolt 28 is inserted into the U-shaped mouth of the U-shaped plate 29, the internal threaded tube 21 is screwed with the movable bolt 28, and the tail end of the internal threaded tube 21 is abutted against the U-shaped plate 29, and the head end of the internal threaded tube 21 is fixedly connected with a straight handle 30 for manually rotating the internal threaded tube 21.

[0034] The diameter of the circle corresponding to the inner side surface of the first clamping strip 19 is larger than the inner diameter of the first connecting ring 17, the first connecting ring 17 and the second connecting ring 18 are symmetrical up and down, the top of the first connecting ring 17 is a conical surface with an inner high and an outer bottom, and the bottom of the second connecting ring 18 is a conical surface with an inner bottom and an outer high. The sum of the thickness of the outer side of the first connecting ring 17 and the thickness of the outer side of the second connecting ring 18 is less than the height of the slot 22, and the sum of the thickness of the inner side of the first connecting ring 17 and the thickness of the inner side of the second connecting ring 18 is greater than the height of the slot 22, so as to ensure that the quick-connect clamp can clamp the first connecting ring 17 and the second connecting ring 18 adjacent to each other above and below.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
